Is your bike STOCK?? Have the Cams been changed? Do you have Stock Cam CHAINS & TENSIONERS, or is it updated to GEAR DRIVEN Cams? Either way, you have a Cam and or Lifter Problem, and if you are not a Harley Mechanic with access to Shop type tools and Equipment, then I suggest you take you Harley to a reputable repair shop for diagnosis and repair. DO NOT CONTINUE TO RIDE WITH THIS PROBLEM, IT WILL NOT FIX ITSELF and will only cause you MORE EXPENSIVE DAMAGE. Good Luck! -Dr.Mark

depending upon your model (sportser or big twin ) the primary chain should be checked for adjustment around every 10,000 miles big twin adjustment is as follows disconnect neg. cable from battery jack and level remove shift lever if necessary remove inspection cover ( replace gasket and o-ring ) also do this with bike at room temp. with rear tire in air turn rear wheel shifting into top gear turn wheel while pushing on change find tightest point on change chain deflection should be 3/8 to 5/8 move adjuster to needed position
That noise may be coming from your primary, not the tranny. Try adjusting the clutch, and (of course) make sure you have the correct amount of chaincase fluid in your primary. If that doesnt do it Change the trans fluid and see if that helps
sounds like you have a voltage drop (that is a loss of power between the start button and the starter solenoid) the wiring on that circuit may be too thin. to remedy this problem you need to put a relay in the circuit. let me know if you want to know the details of how to wire the relay up.
Drain the primary and remove the primary chaincase cover. There are 2 bolts with lockplates and washers thats hold the shoe. Remove them, install the new shoe, reinstall the 2 bolts. The lockplate is installed outside of the washers. Thats it
the tensioners are spring loaded and the springs are real tuff the fiber pad is another story the cam cover comes off easy a gaggle of 3/16 allen bolts the adjuster is on the 7:00 position turn it insert a small allen wrench or nail thru the adj, into the small hole in cam plate to hold it in the loose position pop out old one insert new one
If you have chain Tensioners then you have a Twin cam. This is NOT a job for an amature. Its necessary to take out Push rods which means remove heads or cut your pushrods and reinstall adjustables. You need to take out your cam plate,re align oil pump..Its not a simple job for a novice. If you have noise they have already exploded or are about to. Do not ride your bike..those plastic pieces can get sucked into the oil pump and do major damage. I told that to a customer that was going on a trip he did not heed warning. He got 75 miles they exploded and he bought a new motor.
Some of us here do work on Harley's. You are correct on the gap, and here's enough to get started on the timing. Pull the spark plugs and set the point gap to .018 for 12volt systems, .022 for 6 volts, on the highest point of the point-cam lobe. Turn engine over until the front cyl point cam lobe (the small one) is coming around and getting ready to open the points. Remove the timing plug on the engine and gently turn the engine on the kickstarter until the timing mark appears in the hole. On most earlier big twins it should be a straight line, get it approx. in the center or slightly before.
